Specification of Letters Patent.

Patented Apr. 7, 1914..

Application filed September 19, 1908. Serial No. 453,804.

To all 'whom it may concern Be it known that I, CHARLES BENNION, a subject of the King of England, residing at Leicester, in the county lof Leicester, England, have invented certain Improvements in Machines for Use in the Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes and more particularly to machines for shaping the bottoms or other portions of a shoe.

A particular object of the invention is to provide an improved machine for beating and otherwise shaping the bottom of a lasted shoe to even and compact the upper stock thereon for forming a suitable surface upon whichv to lay the outersole.

An important feature of this invention consists in the provision in a tool having beating devices that are movably mounted in a rotary carrier and are held outward by centrifugal force, of means for guiding or determining the direction of movement of the beating devices under the action of centrifugal force and reversely under the pressure of the work against the acting faces of the beating devices.

As shown in one construction herein the beating devices are movable in a right line from and toward the axis of the carrier and in an approximately radial direction. The path may, however, be varied within this in vention to give any predetermined movement that may be desired, as, for example, to give a movement oblique to the diameter and slightly curved as shown in a further construction. This path permits the beating devices to hang upon the stock as they strike it and then, asv they advance over it, to exert a greater drawing action for forcing the stock inwardly than is provided by the radial guideways.

In the illustrated embodiment of the invention the beating devices comprise one roll or a plurality of adjacent rolls or rings arranged to turn freely upon an axle or rod which is movably held in the hub or end disks of the carrier and guided in radial slots therein. When the tool is rapidly rotated, as, for example, at about 2060 revolutions per minute which appears from eX- periments to give the best results, the beating devices are automatically forced outwardly in the guide slots and as they contact with the work the beating devices turn upon their axles to give a rolling blow to the stock and yield inwardly toward the axis in a direction determined by the guide slots to give an elastic quality to the blow.

A further feature of this invention consists in providing means for holding the beating devices normally in a predetermined position with relation to the limits of their radial movement. This means is shown as comprising yielding devices cooperating with the end disks or hubs and the rods or axles to hold the beating devices normally at the outer limits of their movement. This arrangement maintains the normal cylindrical form of the roll as a whole when it is at rest. The yielding devices also serve another purpose in that they form a constant force holding the beating devices outward on the roll. This force is augmented by centrifugal fo-rce when the roll is in motion, the extent of the centrifugal force varying of course with the speed at which the roll is driven. This speed can be changed according to the kind of work to be done and the quality of blow that is desired. With this construction it is not necessary to maintain a high speed in order to get enough outward pressure on the beating devices to cause them to strike sharp blows upon the work as might be necessary with light beating devices if centrifugal force alone were relied upon to hold the beating devices outward in their guides. The springs prevent the beating devices from rebounding as they strike the stock and thus releasing their edective contact with the stock as they pass over it. This is part-icularly important when the guideways for the beating devices are inclined backwardly relative to the direction of rotation for the springs insure that the beating devices will grip and hang upon the stock as they advance over it and thus edect a drawing or pulling action in the direction of their rotation which is desirable for working the upper inwardly from the edge of the last.

These and other features of the invention, including certain details of construction and combination of parts will appear in connection with the following description of a preferred construction embodying the invention and will then be pointed out in the claims.

Figure l is an end elevation partly in section. Fig. Q is a side view also partly in section. Figs. 3 and 4 illustrate a slight modification.

The machine of which only the driving shaft 2 for actuating the beating roll is herein shown, may be arranged to rest upon a bench o-r be supported on a post. The roll comprises a carrier or hub 4 having end plates or disks 5 having formed in their edges guideways 6, to rece-ive guide blocks 8 which are free to slide therein. The guideways may be arranged as shown in Fig. 1 to extend obliquely with relation to the diameter of the roll, or diametric lines thereon, to permit the beating devices guided thereby to move inwardly and backwardly withrelation to the direction of rotation of the roll. Preferably the guideways will be curved slightly as shown in Fig. l although they may be straight. It is also within this invention to form the guideways on radial lines of the hub as shown in Fig. 3. The guide blocks receive axles or rods 10 which are thus supported for either end to yield independently of or to a different extent from the other. The beatingdevices which are mounted on the axles l0 are shown as rolls 12 free to turn on their axles. Such beating device may comprise a single roll as shown in Fig. 2 or a plurality of adjacent rolls as shown in Fig. 4. The guideways 6 preferably contain springs 14 arranged to hold the blocks 8 and the beating devices l2 normally outwardly to the limits of their movement but yield under pressure of the work against the acting faces of the beating devices. rIhe springs maintain the beating devices in a circular series when the roll is at rest or running slowly. An annular plate on the outer face of each disk 5 has an inwardly turned lip which plate and lip confine the blocks 8 in the guideways 6.

In the use of the apparatus the tools will be impelled outwardly by centrifugal force and a shoe may be presented as indicated in Fig. l in position for the beating'devices to strike the surface which is to be treated. If it is a lasted shoe the bottom of which is to be compacted and evened to form a suitable surface to receive the outersole the shoe may be so held that the overworked marginal portion of the upper material on the in- .nersole will be beaten downwardly and, preferably, inwardly from the edge of the shoe. The arrangement of the guideways by which the beating devices yield back wardly and inwardly permits said devices to hang to the upper as they pass over it and thus increases the inward pull or draft on the upper being treated. The use of the.

springs reinforces the action of centrifugal force and assists in causing the beating devices to hang to the stock and maintain their pressure thereon as they advance over itY instead of rebounding. The beating devices preferably have rolling contact with theV stock so that there islittle liability of their marring it as might occur if they were merely rubbing tools. Y

AHaving explained the nature of this invention and described a preferred construction'embodying the same, I claim as new and desire to secure by Letters Patent of the United States :-l Y
